I think the concussion issue will be one of the larger driving issues of football eventually maybe even going away. The NFL at some point in time will be gutted by the amount of money they end up paying. It will then trickle down to other levels of football and then manufactures of equipment. Asbestos settlements having been going on for years and concussions will do the same thing to football and manufacturers. Not saying it is wrong on right, but what I think will happen and probably not in my lifetime. I enjoyed playing football as kid and in high school. My kids did to, but I have reached the point where I don't think I would like my grandchildren to play. I also believe you see that sentiment growing more and more. It may be 50 years or more but the stadium may be used more for soccer at some point.
